PaY For Play - Essay Example Sports players are a huge asset for the colleges because they enhance the college reputation and prestige. One of the realities of the current university and college system is that they derive a residual level of profitability from whatever sports programs that the school offers. This residual level of revenue has come to be an important funding stream that colleges and universities rely on to ameliorate the economic pressures of hard times. However, regardless of the degree of revenue that these institutions are able to garner as a result of their sports programs, the student athletes are not paid for their work outside the scholarships that they are oftentimes offered as an incentive to play the game. However, it is normally seen that the athletes or sportsmen have not given much consideration when it comes to upholding their rights. When it came to my college, I saw that our college athletes were not given due respect with regard to the reward structure. In our society college ath letes undergo much sacrifice and bring money but not be paid in return. I myself have been a football player in college and I understand what it means to be able to have spending money to survive during the university experience; a luxury that those not playing sports can readily achieve merely by picking up a part time job while in school. Thus, following inductive reasoning I can say that those college athletes who participate in major money making sports, such as football in the SEC, should be paid and not just in kind. The approach of ethos, pathos and logos is used in this paper to prove the point. For logical approach inductive reasoning is used based on facts, ethical appeal is used after considering views of different authors regarding payment of college athletes and an emotional appeal also lies underneath the arguments presented in the paper. Background of Sports Play at College and Problems in Pay for Play: Regulation regarding paying college athletes should be changed in order to compensate athletes and payment should be made mandatory. This is because these players bring in a lot of money and put in too much work for that without earning a paycheck. The idea of sports played in college came into existence during 1850. Soon after, sports achieved its place in the curriculum of the college activities. Gradually colleges started to prepare for the intercollegiate competition as a mean of boosting the self confidence and as a method of learning to overcome the obstacles in life. The first intercollegiate athletic competition held in America was secondary to the promotional wishes and was launched as a commercial venture. It has been regarded as the perfect physical activity and the desire of the young men. The competitive spirit and vigor which are parts of college sports enhanced the mental and physical pleasure of the students. The college authorities elaborately planned sports activities which motivated the students immensely and sports events at c ollege and national levels became a prestigious venture and money making phenomena for college authorities. The media kept the young athletes in the lime light and the scholarship provided by colleges to them stood as a bonus (Smith, 2011, pp. 1-8). However one should consider their importance to the colleges and their role as revenue earners in order to compensate them in cash and kind. Here lies the ethical appeal. Playing college sports has evolved to be an honor

Economic Development in Kenya Assignment Example | Topics and Well Written Essays - 500 words
Economic Development in Kenya - Assignment Example It will also lead to the digitization of the Kenyan education system, where every pupil in Kenya will receive the same quality of education be it in private or public schools and finally Kenyans technological knowledge will increase immensely, and in the future Kenyans might produce one of the best IT innovative gurus, such as Bill Gates or Steve Jobs. Therefore, with this project in mind, the hypothesis that would be tested by the RCT is whether the laptop project will improve the education quality in pupils from rural Kenya and make it at par with that of students learning in urban private schools. The randomized control trials, in this case, will be identifying two schools one from rural Kenya, where there are minimal facilities and learning is a very cumbersome task for its pupils (treatment group). The other school will be from urban Kenya, where facilities are in plenty, and the learning institution has everything it needs to make learning a sweet and enjoyable experience for its students, (control group). The target population will be all pupils joining class one in both schools, where the students in the rural school, will be provided with laptops that have been loaded with adequate learning material and a well-defined syllabus. The same syllabus will be the one student from the urban school will be studying as well, the rural school will also have teachers that will help the students understand how to use and retrieve the information they want from the laptops. After the RCT is implemented, a series of tests will be administered to both the treatment group and the contro l group, where our intended outcome is that the treatment group will perform equally as the control group if not better. Our hypothesis is whether the laptop project will improve the education quality in pupils from rural Kenya and make it at par with thatà of students learning in urban private schools.Ã

Alfred Hitchcock The Birds Analysis
Alfred Hitchcock The Birds Analysis The Birds was one of the most successful suspense films of its time and possibly all time. It is a superbly directed film by the master of suspense Alfred Hitchcock in 1963. The Birds was based on a novella by Daphne Du Maurier of the same name. I think this is an astounding, unbelievably, remarkable film because it does everything a suspense film should have, and more. In this article I am going to explore the suspense used in the film directed by Alfred Hitchcock. I will examine how through lighting, colour and camera angles this was one of Hitchcocks most renowned motion picture. Hitchcock was very impressive in his dramatic techniques because the tension is built in various scenes which also makes this film accomplish the horror genre in addition to suspense. Initially the audience believe the film is a comedy because it is incredibly ordinary in addition to the use of bright lights and warm colours. Hitchcock makes us as the viewer get an understanding of the characters back story before unleashing the terror in the rest of the film. The movie was very modern for its era, as a result of the use of new technology to the 60s hence the scenes are realistic which adds to its unrevealing storyline. The use of Technicolor added to the horror during the film because it was very new. Through pathetic fallacy the atmosphere is set in most scenes, for example when Melanie Daniels and Mitch Brenner are in the bird shop it is very bright and colourful which is reflected in the characters behavior in the scene. Also towards the end the lighting and colour create a dark and eerie atmosphere. The killers in The Birds and Psycho were believable however the characters remained odd and innocent characters. The introduction of the film with the character is familiar shows her sense of security however when she moves to a rural area we see a vulnerable character with unfamiliar surroundings. Hitchcock may have chosen a small town because it is seen to be more dangerous but in this setting it is more dangerous as it is isolated. The film features a mass use of the colour green for example in the scenery whilst Melanie is driving the boat the landscape is green and blue to Hitchcocks liking and also Melanie wears the same green coat throughout the film. This makes the colour green significant to Hitchcocks films. Green is not usually associated with terror and fear but Hitchcock used this to make the audience feel uncertainty in the film. When Melanie is taking the birdcage to Mitch she is viewed from the waist down showing her in a green dress. This is a reference to birds being women because Melanie is blonde haired and is wearing green, the love birds are yellow headed with green bodies. This suggestion is also made in the beginning when Melanie is walking down a busy street and hears a wolf whistle towards her. This sound is similar to a birds sound. Hitchcock also used the colour green in Vertigo the Female lead wears green. Hitchcock also uses sharp objects in many ways for example the beaks in The Bird s and the weapon in Psycho. Most of the film is set during the day which makes the viewer unsuspecting of the birds. Hitchcock does this to show the calm and peaceful atmosphere which is maintained throughout the film until the ending. Vibrant colours take over the screen predominantly, during the relaxed scenes whereas before and for the duration of the bird attacks dim, shady colours are used. For instance in the Tides Restaurant when the birds attack the atmosphere is dark which is reflected on the clothes worn, the weather and the colour of the birds (see image 1). The colour plays a key part in why The Birds is a successful suspense film. Through its use of high key lighting contrasted with low key lighting which creates a mysterious impression to the audience. An example of lighting is offered proficiently in the dead famer scene. In this scene we see the lighting symbolising the mood in the scene. It begins with Lydia walking down with very bright sunlight, as she walks towards the door the lighting begins to dim down. Entering the house we see a window with natural light but no false light in the house. This absence of light begins to suggest something bad has happened. The director has used this superbly in many of his films to create unease with the observer. Hitchcock was superior when it came to using mise-en-scene to alter the appearance of things. The room where the famer is found is bright but as the camera begins to reveal his body the lighting is darker. The shadows cover the body only exposing his face with his pitch-black eye sockets. As Lydia runs out the weather has changed to a dark stormy sky. The audience feels that this symbolises the man has died and the birds will attack again. Hitchcock creates a parallel to the book because the main character finds his neighbours killed because of the birds. The director does this because he is trying to use visual techniques such as camera angles and lighting to create a horror film atmosphere which also creates a more effective suspense film. This scene is effective because of the drama portrayed by Lydia it is also good because we begin to see different aspects to Lydias character. During the scene where the old woman talks about the scientific facts concerning the birds we see bright colours and vivid lighting but as the birds begin to attack it seems to get darker. When the man is set alight the fire signifies death and evil, as well as a warning that more birds are coming to attack. This is another scene where lighting causes suspense. The use of Chiaroscuro is very effective in scaring the audience. Also the use of long dialogue to create suspense is extremely effective because the audience is eager to find out the cause of the attacks and when they will attack again but this explanation creates the anticipating effect on the audience. The MacGuffin changes throughout the film. At the beginning the audience feels the film is a cheerful film about love but when the storyline develops the viewer thinks: Why are the birds attacking? When are they going to attack next? These questions cannot be answered because they were even analysed by the characters in the Tides Restaurant scene after the birds attacked the school but there was no rational reason. Hitchcock used the MacGuffin in many of his films for example in Psycho the characters wonder Where Is Marion Crane with the money? MacGuffin is one of Hitchcocks strong points because he uses it to make the audience have a different attitude to every scene wondering what is going to happen and why is it happening. This works well because the audience does feel the urge to find out what will happen and a number of other questions. The performance portrayed by the actors in this film is very effective as the actors and actresses are very realistic and can relate to the audience through this. Also the use of something as ordinary and everyday as birds instead of monsters and aliens used in modern films makes the film relate to the audiences life. This is a film that can affect a wide range of audiences because it would have frightened people in the 60s because of the fear of bombs attacking. Nowadays it could be a relation to global warming attacking us. Due to the death of the farmer Lydia was in more need of Mitchs protection but felt she had to compete with Melanie because both were women in Mitchs life and they felt helpless. The very moving portrayal of a needy mother by Jessica Tandy is amazing and still makes an impact to people today because this emphasises Oedipus complex. Mitch is the central character and the women seem to revolve around him which could be another cause for the bird attacks. The protagonist in the novella by Du Maurier is a farmer and Mitch lives in a barn. This is one of many similarities between the film and the book. Hitchcock developed the characters relationships in different ways to create an unsuspecting atmosphere. Melanie is the centre of this as she is a problem to Lydia Brenner and Annie Hayworth (the school teacher) as they are both women who are dependent of Mitchs love. Kathy Brenner (Mitchs sister) likes Melanie because of the love birds she received from her for her birthday and is not one of the main focuses of the film. The handing of the love birds guides to a very misleading storyline making us think it is about the love birds only because Hitchcock spent a lot of time building the characters feelings and behaviours to create an intense atmosphere for the audience thus creating suspense. In the opening credits the title The Birds was slowly pecked away by the passing crows. This use of bright light and medium shots for an introduction creates a mysterious tone for the audience. For modern audiences this could be seen as a very emotive film but long however this makes the audience even more eager to watch the film because it does not give away much information in many scenes. The power of the movie is through the use of camera angles due to the absence of a music soundtrack. Hitchcock uses a variety of methods which are incredibly effective to produce the vast suspense in the film. In many scenes tension is built to create fear and uncertainty in when the birds attack. The film is not extremely graphical in the scenes where the birds attack yet the terror is shown through his use of camera angles. For example Melanies phone booth scene, the camera moves around in the point of view of the birds then switches to Melanies view however when she is getting more and more vulnerable low angle shots are used to make her look defenceless (see image 2). As Melanie enters the phone booth a medium long shot is used. Birds-eye view is used to show her alone with the birds attacking the booth. Extreme close ups show her emotion as scared. The attack from the birds is shown with fast paced point of view shots from Melanie and the birds. Extreme close ups are used to show the characters emotions during bird attacks. At the start of the film this is used showing the characters behaviour. Predominantly when we see Melanie she looks like an upper class woman with no worries in the world through extreme close ups. She is very sophisticated which makes her weak and in danger of attack. Hitchcock uses a female protagonists in many of his films such as Psycho, Marion is alone and vulnerable and Vertigo, the female is calm and alone. Through camera angles we can see the similarities in the characters feelings. Point of view shots are used a great number of times during the film to give you an idea about what they can see and how they see things. For instance when Lydia sees the farmer we walk with her because a point of view shot is used. The body of the farmer zooms in three times to show his eyes. This triple close up shot works well with point of view shot to create a tense atmosphere. Lydia is a frightened old woman who walks in a certain way through Camera angles we find out about her need to be a woman in authority. In the playground scene of The Birds the camera shots are used to develop the still surrounding before the assembly of the birds. The long shot of Melanie Daniels walking to the bench illustrates she is alone and the empty climbing frame in the playground. She is unaware of what is going on and has her back to the birds in the climbing frame (see image 3). By doing this suggests she is exposed and vulnerable and open to attack as she is unaware of the further gathering of the birds but the audience can see this through the medium long shot. She is lower down under the birds showing she is in danger of attack by the birds. Hitchcock is trying to explore the audiences reaction to this calm place being the home of the villains of the film because the playground seems like a place of purity so the audience believes it is a cheerful place. Usually in suspense films something begins calm but changes unsuspectingly. Hitchcock used suspense to its extent because the wait in many of his scene s for the birds to come are long. This change is when the first bird lands on the climbing frame creates a sinister atmosphere. The camera cuts from mid shots of Melanie smoking and the birds building up number on the climbing frame. Mise-en-scene is used because Hitchcock makes the landscape reflect onto Melanies loneliness. The school playground and the hills in the background make the atmosphere normal and make her appear defenceless and alone. Hitchcock is trying to explore how colours and bright scenery creates a cold scary atmosphere without the use of non-diagetic sounds or speech of Melanie. The argument that the bird attacks are drawn by Mitch could be proved wrong as it has three female characters: Kathy, Melanie, Annie. The sounds are very loud and show tension such as in psycho the only sound in the shower scene is the water touching the basin. Melanie is a very vulnerable character because she is an outsider to the community and Hitchcock emphasises this in many scenes. Annie seems to be dominant and have power over Melanie because she is accepted by the community. Also Annie feels threatened by Melanie because we see her ordering Melanie to sit outside instead of staying with her in the classroom. Tilted angle shots are used in the end scene when we hear the birds approaching. The characters look up towards the ceiling where the bird sounds are coming from. The squawks could be a diegetic or non diegetic sound because they set the mood and as the volume increases the characters are more frightened and the mood is intense. Afterwards a low angle shot is used to show the defencelessness of the characters. Wide shots (Extreme long shots) are used to show the landscape and the characters surroundings and usually it is not visibly detailed. This is incredibly thrilling and terrifying and is shown in many scenes to show the birds plotting and attacking. A birds eye view camera angle is a very strange and unnatural shot but is used frequently in the film, not only in the phone booth scene (see image 4). Hitchcock could have used this as a literal birds-eye view however the shot puts the audience in a god like position because we see it from above. This could be a direct link to the judgement day explanation of the film as this shot is used when the birds begin attacking at the gas station. The first attack is referenced in the Tides Restaurant scene when the woman accuses Melanie of the bird attacks because she is the first person to be attacked in the boat. Long shots are used to show the landscape. The warm, calm atmosphere in the scene is shown by the landscape and Melanies clothing. The long shot doubles as a point of view shot for Mitch. We see what Mitch sees as she is attacked by a seagull. The bird attack could be interpreted as Melanies need be noticed by Mitch because Melanie would have gone home straight afterwards if it wasnt for the bird attacking her. Hitchcock uses a range of dramatic techniques to introduce the characters and their relation with each other. He does this to create a sense of unease and make the film have a deeper meaning than just bird attacks. This film could be about a number of other things because this scene shows the emotions between the two characters which seems to cause the first bird attack. If Hitchcock really wanted to make th e film only about birds he would have based it more around the book because the novella has a conclusion and an explanation. Also it focuses more on the bird attacks and the science than the relationship between the characters. The mother and son relationship is shown in many of Hitchcocks film for example the dominant mother in Psycho. Throughout the film Mitch refers to his mother as darling and kisses her frequently. This is a suggestion of Oedipus Complex. Mitch is in love with his mother and the absence of his father makes the mother needy. In addition to that Lydia and Melanie look extremely alike which tells us that Mitch wants his wife to be his jus like his mother. One of the most successful scenes in the film is Kathys birthday scene. It has a sense of being a very unsuspecting scene because it uses very vivid colours and has an absence of birds altogether in the landscape. This use of bright lights and bright colours make the scene seem innocent which makes the audience anticipating a bird attack or wondering why they arent attacking. This gives an idea of innocence because we see Mitch and Melanies relationship develop before the bird attack and we see their characters revealed which also adds to a build up to the climax of the birds attacking. We see Lydia is helpless by the uses of camera angles such as point-of-view shots and extreme close ups. She is scared when the birds begin to attack and is needy of Mitchs attention but he is focused on the other two women in his life Melanie and Annie. When the birds pop the balloons we hear sounds like bombs which could be a link to the Daphne Du Maurier novella because her book was based in Englan d to show the fear of bomb attacks in post war Britain. Hitchcock was trying to explore what humans are afraid of which is nature attacking the human race. Hitchcock played on the idea of being afraid of the sky and used birds instead of bombs. This scene shows how the director makes a calm peaceful scene make us think about the world and nature. Modern movies have followed this example by the master of suspense such as 2012 which shows nature attacking humans and ending the world. Towards the end when the birds attack the house the feeling of being paranoid is conveyed through the actor which implies the feeling of things coming out of the sky. This is a reference to the cold war. This also makes us as humans feel that anything can happen to us and nature can make us vulnerable. The book comes to a conclusion that the birds are influenced by the tide levels. In the beginning the humans are in control of the birds as they are caged. The tables turn when the humans are locked in their homes with the birds intimidating them. The Birds is arguably a film about the tension between families because the birds attack when different things happen to each character. The bird attacks when Melanie starts to get feelings for Mitch and when there is tension between Lydia and Melanie. Lydia is the overprotective mother and Melanie is a woman without a mother. Melanie is wealthy and has everything she wants apart from a mother. At the end we see Melanie powerless she can barely look up to Lydia but still does in a way saying that she has found her mother figure and is need of help. Also another interpretation of the bird attacks is that because the birds will never stop until humans change. The birds almost fight back after the humans treat them with cruelty trapped in zoos and cages. The phone booth scene also emphasises that because Melanie is surrounding by birds mocking her in a phone booth which looks like a bird helpless in a cage. This tells us there could be a biblical message to the film, Judgement day as discussed in the Tides restaurant. In Psycho, there is a psychologist who concludes the film by explaining why Norman Bates chose those actions, similarly The Birds an ornithologist explains the facts about birds and possible answers to their behaviour in the Tides Restaurant. The birds could be a warning from something greater than humans due to the fact that birds are traditionally a symbol of peace but in the film they connote death and evil. Hitchcock reinforces the idea that humans are in constant fear that nature will turn against them. Humans a re usually the predators of birds but in the book they are shown as eating the humans because of the weather. However in the book they kill the humans but no mention of eating. The humans are left helpless to die. Hitchcock could have also based this on the bird attacks in San Francisco because the birds attacked without an explanation. Also Psycho, Normans hobby is stuffing dead birds which could be a reference to the cruelty of humans to birds. In the beginning the lack of any non-diegetic sounds in the film makes us believe there is no music score. However Hitchcock uses the sounds of the school children and birds during the film. The squawking of the birds is very intense. When it is calm the sounds are quiet and high pitched. Before and during attacks the bird sounds range in pitch and volume terrifying the viewer. Hitchcock refers to Bernard Herrmann, a composer as a music consultant. Herrmann has worked with Hitchcock on many films such as Vertigo. Hitchcock seemed to not use non-diegetic sounds to create a nervous atmosphere which is preserved throughout the film but the bird noises seems to be internal but is a non-diagetic sound with different pitched squawks. When we are introduced to Mitchs family home Melanie on the piano is another sound which creates and atmosphere. Whist Kathy is pleading for Melanie to stay. The piano sets the mood and slows down in pace as Kathy is turned down. In the Playground Scene the childrens nursery rhyme is the only sound which gives the same effect as a non-diegetic sound. This sound is well used to create tension in the atmosphere. The children sing repeatedly to make the scene feel innocent and to show Melanie is still naive to the birds gathering behind her. Although the sound is internal it still builds up tension and fear in the film. To conclude the film was incredibly triumphant in creating suspense for the audience. The whole film has a mixture of horror and suspense. This made me feel Hitchcock deserved to be called the master of suspense. Although others may feel this is not one of Hitchcocks best films because of bad visual effects I think it is worthy of being in the top five of Hitchcocks films. Through camera angles, colour and lighting and the drama portrayed by the actors and actresses the birds continues to be a success due to it being able to frighten audiences from different time periods. The absence of a musical soundtrack is very efficient in creating suspense. The film also produces an amazingly compelling storyline and for those reasons Hitchcock will never be forgotten for his amazing works.

Confederation vs. Federation The need for change :: essays research papers
The US government transformed itself from a very weak government to a strong central government from 1776 to 1876. The maitenance and creation of order was deeply needed in america at this time. Due to the US Constitution, The Articles of Confederation, and the Bill of Rights America went through so much needed changes. Around 1776 America wanted a weak government because they had such a fear of monoarchy. When the trasformation of the new strong central government began many more problems occured and even contributed to the Civil War. The first attempt for a new government was in 1781 when the Articles of Confederation was formed. The Articles of Confederation was like a contract that bounded the 13 colonies together which gave each individual state power over its own decisions. Some conflicts arose from this. So, the next step was the creation of the US Constitution. The Constituion was a set of laws that defined the powers of the government. This fell through when there was nothing mentioned about slavery. Many, many conflicts arose from the states slavery issue. After much thought it was deceided to come up with a comprimise. "For every free state there will be a slave state". This seemed to work until Lincoln was elected in 1860 and then slavery was abolished. This played a key role in the beginning of the civel war where 600,000 people lost there lives. This is a great example of why the Constitution had failed. So the 13 amendment was formed and slavery was officially abolished. Now around 1865 America was in great need for some reconstruction. With the states having their local powers revoked they did not want to lose their right to life, liberty and the persuit of happiness. With the new central government in control new federal supremacy was formed and initiated new checks and balances to ensure the government was running properly.

Innocence in Catcher in the Rye Essay
In JD Salingerââ¬â¢s Catcher in the Rye, Holden Caulfield is a boy aimlessly traveling New York City after being expelled from a classy boarding school. Holden poses a great deal of trepidation when it comes to sexual relationships, especially those of Jane and Sunny. Furthermore, Holden tends to misjudge the maturity of his fellow characters. The combination of this misconception, the tension between sexual trepidation, and an adult life with adult relationships, results in confusion for him. In Holdenââ¬â¢s life, there have only been a few people heââ¬â¢s cherished more than his childhood neighbor, Jane Gallagher. They were close childhood friends, and when his roommate Stradlater brings her up years later in high school, all he can talk about is the innocent fun they used to have: playing checkers, watching her dance ballet in the summer heat, and how her Doberman always came into his yard. However, he also reminisces on how her ââ¬Å"boozehoundâ⬠stepfather would always ââ¬Å"run around the goddam house nakedâ⬠(42). He suspects that her stepfather had harassed Jane, who ââ¬Å"had [a] terrific figure, and [he] wouldnââ¬â¢tââ¬â¢ve put it past that bastardâ⬠(103). This really bothers Holden, as does when Stradlater insinuates that he made sexual advances onto Jane on their date. To Holden, sexual encounters mean an adulteration of innocence, and he hates that Stradlater or Janeââ¬â¢s stepfather may have corrupted Jane. Many times, Holden promises himself that he ââ¬Å"outa go down and say hello to herâ⬠(40), or that he should ââ¬Å"give old Jane a buzzâ⬠(195), but he never does. Subconsciously, he fears that Jane will have grown up, and calling her or seeing her will surely alter the young, innocent, checkers-playing version of Jane that he has in his mind. This is confusing for Holden because Jane has grown up, yet he still thinks of her as a little girl, not the grown woman that she is. Holden ââ¬Å"knew that she wouldnââ¬â¢t let [Stradlater] get to first base with her, but it drove [him] crazy anywayâ⬠(104). This shows Holdenââ¬â¢s potential misconception of Janeââ¬â¢s innocence. It is unlikely for a post-teenage young woman to be as sheltered and have as much innocence as she did when she was a little girl. However, this is something Holden cannot grasp. This dilemma is a direct result of Holdenââ¬â¢s irrational respect for innocence, influenced by sexual confrontations in Holdenââ¬â¢s past. When Holden agrees to have a prostitute come to his room in the hotel, he is soon greeted by Sunny at his door. Holden is immediately unimpressed with Sunnyââ¬â¢s maturity; how she was ââ¬Å"jiggling this one foot up and downâ⬠, she ââ¬Å"never said thank youâ⬠, and she ââ¬Å"had this tiny little wheeny-whiny voiceâ⬠(123). He also notices that she appears very young, and said things that were really childish. This ends up making him feel ââ¬Å"more depressed than sexyâ⬠(123), and he decides not to have sex with her after all. The depiction of this young girl making money as a prostitute seems to upset Holden, and he ultimately concludes that having sex with her would spoil her innocence. This is where Holden is again misguided. Just as it is unlikely for Jane to retain the same degree of innocence through the years, it is improbable that Sunny, being a prostitute, will have not had sex with many people in the past, therefore preserving her innocence. But all Holden can see in Sunny is the childish and immature, which results in a conflicted view of the world. The importance of innocence to Holden is something that results in nervousness towards othersââ¬â¢ sexual identity and activity. His perspective of Jane and Sunnyââ¬â¢s innocence is also misguided to the point where he sees innocence in them when there is none. Overall, the importance of innocence to Holden results in contention that is less than innocent.

PEACE Domestic Violence Agency Essay
The PEACE Domestic Violence agencyââ¬â¢s mission is to ââ¬Å"reduce victim trauma, empower survivors, and promote recovery through direct servicesâ⬠(University of Phoenix, 2012, para. 9). Also, according to University of Phoenix Appendix B (2012),PEACE also strives to reducing the occurrence of sexual assault and domestic violence by educating the abused and the community and proposing ways to fight against social norms and beliefs. It will reside in the city of Portland, a large metropolitan city, that has been experiencing a rise in reports of not only domestic, spousal, and child abuse, but also youth violence, assault, and road rage over the last five years. PEACE is looking for funding from the National Foundationââ¬â¢s funding program and by doing so strives promote the well-being of people whose lives have been affected by domestic violence, improve the quality of life of families with a member in prison, provide people who are (or have been) involved with the criminal justice system with a rehabilitation program where they can obtain the skills and support networks needed to lead fulfilled lives. ââ¬Å"The Small Grants Program offers one-time grants of up to $5,000 to registered charities with an annual budget under $500,000 and the Investor Program is an innovative funding program designed to support six organizations under each of the objectives of the Supporting Families program, with up to $150,000 a year for up to 3 yearsâ⬠(University of Phoenix, 2012, para. 11). The program needs not only proper funding but the ability to allocate that funding in ways that will benefit the community in the fastest and most effective way possible. Because of this, PEACE will be looking into alternative funding. The Community Innovation Challenge is one of the most important ways PEACE will try and obtain nontraditional funding. The Community Innovation Challenge is a grant program that gives approved organizations money so they can enact faster and more efficient ways of serving and bettering the community. This kind of funding would benefit PEACE because a domestic violence agency like PEACE is helpful to the community on so many levels ââ¬â children to adults to those looking to be rehabilitated. PEACE would be a prime candidate for this grant because of this reason and the money would be used to assist workers in their education on the matters at hand as well as paying for more workers if the organization gets too large for the current staff amount. PEACE will also be looking into outsourcing and setting up charity booths at frequently visited locations like outside a grocery store or at a shopping center. Sending emails and/or letters to local businesses, companies, and even other organizations looking for financial assistance, ideas, and information is definitely helpful and it also allows smaller businesses to get their name on the map and helping out the organization if they were to become something like a sponsor. Setting up charity booths also allows people from many different walks of life to see my programââ¬â¢s cause and contribute something, anything, if they can. Funding from these two sources can normally be used in many ways but it is also not always a large amount. Access to smaller amounts of funding gives PEACE ways to buy low cost items when they are affordable. Things like more seating, chair cushions, water tanks, even coffee and muffinsâ⬠¦ All these things can help people feel more welcome and safe which is important with organizations like PEACE. Signing up for a few free subscription/database-type sites will give access to funds as well. These websites allow a program to look for nontraditional sources of funding as well as give them updates for when new opportunities come up that apply to the program. This is especially helpful for busy programs that may not have the man power to go out and hunt for funding sources while also working with the program as much as The mission of the PEACE Domestic Violence Agency is to reduce victim trauma, empower survivors, and promote recovery through direct services. Their curriculum is based largely around the need of the community and they set out to provide the best, most varied care they can. Starting with professionally trained staff who are looked over by a small administration PEACE locates those in need of assistance and brings them to a place where those needs can be met on an individual basis as well as on a group basis. The stakeholders for PEACE start with the administration and staff of the agency who put themselves on the line taking care of their clients and looking for sources of funding to make sure things are taken care of. Staff and administration need to have their physical and mental needs taken care of and provided for so they can then provide for the community. This may mean more staff need to be trained and employed to keep everyone at the top of their game or the spaces available for clients needs to be cut so staff do not find themselves over-taxed. Domestic abuse is a very serious thing and it cannot be taken lightly by anyone. One false step ââ¬â be it a forgotten case notebook, a less-than-attentive staff member, or what have you ââ¬â can severely endanger the clients. It is imperative that the clients are put into the hands of fully educated, completely able staff. A majority of funding sources are open only to non-profit, 501(c)3 organizations. These organizations must also be in good standing to receive funds and therefore PEACE is eligible to apply for this type of funding. A private foundation is deemed to be any non-profit that supports the work of public charities through the award of grants (2009). In order to receive funds a foundation is required to file a Form 1023 with the IRS. Form 1023 is a 28 page form gives the IRS the information they need to conduct audits of the foundationââ¬â¢s activities. The duty of staff and the administration is to make sure the program meets the requirements of the funders constantly because they would lose funding if they have anything that presents itself as a conflict of interest of it there is anything going on that the funders do not like (2009). Non-profit organizations and their boards are bound to very strict rules and therefore discrimination against an individual or treating a group better than another individual or group can result in the foundation being shut down. Records of a program must be maintained in accordance with Generally Accepted Accounting Principles (GAAP), including the filing of an annual Form 990 with the IRS. All members of the staff and management are responsible to the rules for non-profits. Documentation has to be well understood and applied consistently and correctly. The administrators of PEACE have to find evaluators that can ensure the evaluations show an honest picture of the group effort, effectiveness, and c ontribution to the community so granters can rely on the information provided. The Family Violence Prevention and Services Act is an example of such a funding foundation that can create such a picture. Their mission is to decrease the occurrence of domestic abuse as well as to increase well-being and progress in society as a whole. This foundation is federally funded often pulling in quite a few million dollars that are then allocated to them by the government as well as allocated to sister organizations and other funding opportunities. Being federally funded there is a close eye on the limited resources of the foundation so the funders can be sure the money is spent in the most effective manner to benefit the greatest number of people. The Family Violence Prevention and Services Act serves organizations and people all over the United. The foundation has control over where their money is used and they try to concentrate their focus on organizations that will benefit the community around them the most. They, more specifically, tend to fund essential services that sit at the core of ending domestic violence. Emergency shelters, hotlines, and advocacy as well as primary and secondary prevention are all looked at highly. Another stakeholder in the PEACE Domestic Violence Agency is the community itself. Community evaluation will be an active part of the results that affect ongoing funding by attending the program, first of all, and also by giving feedback on the effectiveness of this program and the staff of said program in their community. The input of the community needs to be taken into consideration when looking at progress evaluations and data that has been collected before making decisions to change, mend, or modify the program. Community member have the biggest input on when, where, and how group sessions are bei ng held and, more importantly, when, where, and how private sessions are being held. Children cannot be expected to want to sit through late meetings, parents may not have time during the day because of workâ⬠¦ There are so many factors that need to be looked at in order to please the wants and needs of the community. This will be important also keep constant monitoring of to allow individuals and families to have time for different kinds of activities and help, as well as to allow the help theyââ¬â¢ve currently received (or have been receiving) to process and sink in. However, the community cannot affect or change the goals of funding institutions. Therefore, they have to work with the funderââ¬â¢s restrictions and requirements so that no single group is held in a higher spot on the list of things that need funding or the list of people that need assistance. Every one of the stakeholders at PEACE Domestic Violence Agency has an effect on the design and implementation of the program. The community, the clients, the staff and finally the administration all s hare a common goal and they all hold the progress and fate of the program in their hands. They all want to see an improvement in the society, they all want to see higher quality of life, and they all want someone (even themselves) to feel safe when they go to sleep at night. This means strong staff, an introduction of life skills, increased community involvement, increased collaboration with funders and the state, a reduction in high risk behaviors, and a decrease in the amount of reported domestic abuse cases. By taking these things into account PEACE Domestic Violence Agency will be a long lasting, effective program. Program planning and evaluation process can provide opportunities for program improvement because they will catch instances of the program not meeting the expectations of the funders, workers, and the community. It is vital for PEACE to carefully create a program plan because, with an organization that is helping a myriad of kinds of victims of domestic abuse, it is easy to give the wrong message to workers and the community. PEACE also provides assistance to people who are looking to be rehabilitated so it would be bad for them if their organization came off as only being there to help the hurt or, in my opinion, even worse: As being there to make sure the people know they did wrong but not actually help them. The evaluation process can keep track of the kinds of clients they get and also what places might need improvement. As the manager of a program anything that improves efficiency and the method for delivery of the service is helpful and those can be found through the evaluation process. As a funder, you would have every right to speak up if you thought your money was not being well spent. This comes into play first in the program planning because if you are looking for a specific kind of program you can gladly put forth an effort to make that happen whether it be with time, money, or both. It also comes into play with the evaluation process. As a funder it would be part of your responsibility to check where funds are going and when and to check if there are more efficient and helpful ways of delivering the funds and how they are spent. Outcome Measure: Reduce the amount of domestic violence report, to assist people and families in dealing with life after abuse, and to help with rehabilitation and reintroduction. * Baseline Data: Portland has experienced increasing reports of domestic and youth violence, spousal and child abuse, assault, and incidents of road rage over the last 5 years. * Evaluation Design: Trained observers, staff * Source of Information/Instrument(s): Police reports, reports from other domestic abuse locations * Who Will Collect the Data: Collection of data will be done by a small team of staff specifically brought together to gather and process data. * Timing of Data Collection: Overall data collection every three months (to look for progress) with an update to data made every forty-five days. * Population or Sample: Population (Applicable men, women and children of Portland) * How Will the Data be Described/Analyzed: Total new/repeat counts of domestic abuse in the form of percentages (increase or decrease) Process Measure: Number of staff trained to handle the abused * Source of Information/Instrument(s): Training sign-in sheets * Who Will Collect the Data: Administration assistant will help participants sign-in * Timing of Data Collection: Before the training session * Population or Sample: Population (all participants) * How Will the Data be Described/Analyzed: Total number of staff properly trained. Process Measure: Number of sessions delivered per group * Source of Information/Instrument(s): Staff session logs * Who Will Collect the Data: Staff * Timing of Data Collection: During and after each session * Population or Sample: Population (all staff will fill out session logs) * How Will the Data be Described/Analyzed: Frequency of sessions per group per staff, as well as an average frequency of sessions across the board. Process Measure: Measures of program fidelity * Source of Information/Instrument(s): Trained observers, staff checklists, client surveys * Who Will Collect the Data: Trained observers, staff, and clients * Timing of Data Collection: Trained observers will attend one session per group each month and staff and clients will fill out biweekly checklists and surveys * Population or Sample: Population (All staff and willing clients as well as observers) * How Will the Data be Described/Analyzed: Qualitative data from observations and data collected from checklists and surveys will be compiled, summarized, and given to administration to show who is being passionate and faithful to the cause as well as what improvements need to be made and where. This evaluation plan will include process evaluation, outcome evaluations, formative evaluations, and summative evaluations. Process evaluations will evaluate all procedures and tasks involved with implementing these programs. Process evaluations will also monitor the program and ensure feedback throughout the length of the program. This is exceptionally beneficial when running a program that is solely need-based and those needs only discovered through dealing with the clients the program is trying to help. Without feedback process cannot be made and goals, no matter how small, cannot be achieved. By performing process evaluations on the effectiveness of the groups as well as the staff themselves and comparing that to data collected by clients the best possible steps can be made towards the goal reducing the effect of domestic violence on Portland. Outcome evaluations will collect quantitative and qualitative data from ongoing programs to document any short-term results that have been achieved as well as open doors to any new short-term goals and changes that have to be made to current ones. Task-focused results such as the number of staff who put their name on the sign-up sheet to be trained, how many clients return, and how many young adults seek help with rehabilitation on their own describe the output of the activity and short-term results, like the percentage of clients that are willing to fill out an end-of-session survey, describe the immediate effects of the program on the community. Information such as an increase in knowledge, changed in attitude, and behavioral shifts are part of a long list of data that can be discovered after an outcome evaluation. Outcome evaluations will come in handy the most when trying to figure out if the community is being reached properly and clients are being treated as best as they can be. It will also be helpful determining what activities are out-of-date or just plain not helpful anymore and what activities can take their place. Formative evaluations, which include pre-testing and competency exams, allow an organization to assess the strengths and weaknesses in their approach to their goals, staff, target audience for their services, and even their advertising campaign! Formative evaluations also help an organization discover if any changes need to be made, if they can be made, or if the program is not going to succeed. By testing messages, products, and services on small groups also helps an organization work out kinks before implementing it on a larger scale. By taking the data gained from a finished formative evaluation an organization can get a better idea of their company, its workers, and its clients and will help them decide if it is better to sink, or hopefully more often, swim. Summative evaluations include any combination of measurements and judgments that allow conclusions about the impact, outcome, and benefits of a program or method. Allowing an organization to stick to such an out of the box, abstract, non-linear form of evaluating it can pick and chose what will get them the most information the fastest. This can be, by far, the most efficient way to help an organization make progress. With an organization that has a lot of different sections, like this one, it can produce the best progress reports because there is not a single mainline format that has to be followed; Just whatever works. I believe I would find pre-post surveys with questions that have people rate things one through five, attendance sheets, and tally sheets to keep record of happenings the most useful. In an organization that has sections that help polar opposite cases (e.g. young adults straight from walking the line of a criminal who wish to find assistance in becoming rehabilitated and young mothers who have been abused and who have children who were abused that are looking for help with learning how to get through their fears and move on with life) there cannot be one set way to document things. Surveys will always be near the top of the data collecting tools list because people can put whatever they want however they want and can truly express themselves if they so chose. An organization cannot necessarily ask two groups, like the two mentioned above, ââ¬Å"How did you feel when the counselor asked you to talk about your personal experiences with being abused,â⬠because the young adult who is looking to be rehabilitated may not have been abused. Attendance sheets are a very important part of an organization as well because it will allow the organization to know how many people they are reaching and if they need to step their game up or not.

The School of Athens essays
The School of Athens essays Raphaels School of Athens is considered by many modern art historians to be the absolute masterpiece of the Renaissance. It is the perfect pictorial counterpart to the enormous changes in thinking that came about in the 1300s as a result of economic and technological developments. Its rational perspective and secular subject matter embody the rediscovery of ancient Greek and Roman culture. The new emphasis on individual thought and expression is also evident in the paintings focus on reason. The Renaissance, which modern scholars place between 1300 and 1600, marks a period of rapid growth and development in Western Europe. In the late Middle Ages, population growth and contact with other cultures through military efforts, such as the Crusades, brought about a revival of commercial trade. Italian merchants began to exchange luxury goods and other commodities, such as fish, furs, and metals, in the Mediterranean and across the North and Baltic seas. Towns began to grow and prosper along the major trade routes, and by the late 1300s, these towns became important and wealthy commercial centers. Towns like Florence, Venice, Milan, and Genoa developed into prosperous city-states that became the centers of thought and culture in the Renaissance. Trade allowed Italians to experience the world beyond their city limits and created an environment that was more open to new ideas and to innovation and experimentation. This exchange of ideas set the stage for the monumental cha nges in artistic, social, scientific, and political thought that came about during the Renaissance. The word renaissance literally means rebirth. The idea of rebirth refers to a revival of interest in ancient Greek and Roman culture. During the Middle Ages, people had been guided by the teachings of the church and were mainly concerned with actions that would lead them to heavenly rewards. Since books were ha...

Also it is important to mention that people, according to the text, view cereal not as a luxury item but as something basic. They rather pay less than buy for a more elaborated cereal. How should I believe Kellogg should diversify their products and make a premium line and a more basic with lower prices but with Kellogg quality.

Bloom taxonomy
Bloomââ¬â¢s taxonomy or also known as the revised bloom taxonomy is a great teaching tool to use when teaching patients about their illness. It consists of three categories and then multiple sub-categories. Blooms taxonomy addresses not only the patientââ¬â¢s readiness to learn but it address the appropriate approach to each individual situation. It gives a systematic way of approaching a topic and the audience that will be learning. When this method is applied to nursing it is a great tool. This is due to the fact that each patient has different cognitive factors, different psychomotor factors as well as an affective domain. Bloomââ¬â¢s Cognitive categories have to do with how the mind can process or regenerate the information provided during a teaching session. There are six sub-categories to the cognitive category. The six are remember, understand, apply, analyze, evaluate and create. A teacher should be able to determine where in this pyramid is the patient. What teaching strategies must be changed and modified to fit the patient lifestyle. The second category is the Affective domain. This is how patients address their emotions to specific problems. This will show what a patient or student values and what motivates them to be who they are. This category has five sub-categories receiving, respecting, valuing, organizing and internalizing. This is the category that will determine if the patient is willing to accept this disease or new lifestyle change into their life. This will tell a teacher where on the scale the patient is willing to rate their disease and how it will affect their life. The Third and final category is psychomotor. This tells the teacher if the patient is physically able to complete the task asked of them. This will allow the teacher to gage if the patient is able to successfully complete what is needed of them to live with their disease process. There are five sub-categories imitation, manipulation, precision, articulation, and naturalization. There is a great example of this category, teaching a patient to use a new nebulizer treatment. The patient will go through reach step of the process till theyà can finally reach the goal of naturalization. Conclusion Blooms taxonomy learning tool can break down the heart of teaching and give it meaning to apply to most any professions. Nursing is just one of those professions that teaching is a large part of the job, on a daily basis. Blooms taxonomy should be used each day on a nursing unit from the admission date to the discharge date.

Community Assessment - Prevention of Hypertensino in adult population Essay
Community Assessment - Prevention of Hypertensino in adult population - Essay Example The measurement of blood pressure is a complex topic, and there is also no exact differentiation between individuals ââ¬Ëat riskââ¬â¢ from blood pressure-associated morbidity and mortality, and rest of the population. Adequate treatment of High Blood Pressure (HBP) with strict adherence to regimen, better prescribing and compliance, and regular follow-up is expected to reduce the risk of stroke and cardiovascular episodes. However, literature reviews suggest that healthcare outcomes and patient compliance are not up to the expected level due to several barriers to the successful diagnosis, treatment, and control of hypertension encountered by healthcare providers and lack of compliance by patients with hypertension. Research findings also suggest that there is disagreement among physicians regarding definitions of hypertension, and confusion over medications for BP control. As such, it is essential to maintain uniformity in research standards and clinical approaches to improve the quality of care for controlling patientââ¬â¢s blood pressure and introduce nurse-led blood pressure management initiative, to attain the goals of Healthy People as envisaged. Hypertension is prevalent in ââ¬Å"28% of the US population and 35% of the African American population. However, only 1 in 4 patients with hypertension are controlled to a blood pressure of less than 140/90 mm Hg.â⬠(Wright et al, 2002, p.1636-1643). Cross-sectional analysis of national representative data by Wang & Wang (2004), conforming to new classification of blood pressure levels by Joint National Committee (JNC) on Prevention, Detection, Evaluation, and Treatment of High Blood Pressure report (JNC 7 Report published in 2003), found that ââ¬Å"elevated blood pressure is a serious problem in the United States. Approximately 60% of American adults have pre-hypertension or hypertension, and some population groups, such as African Americans, older people, low-socioeconomic-status groups, and overweight
Financial Reporting in the Face of Accounting Scandals Essay
Financial Reporting in the Face of Accounting Scandals - Essay Example The job of financial reporting is to give an overview of the short and long term financial position of a company. This is done by producing the Balance sheet, which provides a picture of the company at a point in time, the Income Statement which gives an account of the business's performance during the year in terms of revenues and expenses, the Cash flow Statement which presents the cash inflows and outflows fro the company divided into operating, investing and financing activities and finally the statement of changes in equity which basically explains the change in a retained earnings of the company during the financial year (Graham 2005). These four statements are aided in understanding by notes to the financial statements which provide additional and in depth information about specific items mentioned in the four statements. Accurate and transparent financial reporting of a company's accounts is significantly important in this age of massive investments. The four statements listed above provide information to the investors in making important investment decisions and to lenders regarding credit decisions (Piotroski 2000). This is done based on the position of the company presented in the financial statements which allows investors to judge whether the company is profitable and whether they would be able to get a significant return on their investments with this company. Creditors similarly can judge the ability of the company to pay off its debt in the future and whether they will be able to receive their money back with the interest payments. These statements are also utilized for assessing the cash flow prospects of the company as well with the same purpose in mind, to benefit investors and creditors. Cash flow projections are very important for decision making as cash inflows and outflows are ultimat ely the most important things in terms of a company's ability to payoff investors and creditors. Without this liquidity, there would be little to payoff with (Kaplan 1995). Furthermore, financial reporting gives information about the ownership of assets of the company and its related liabilities which allows users of the statements to assess what the company holds and how it is performing in general. It is also an indicator of the management's performance during a fiscal year, allowing shareholders to judge whether the current crop of management and the Board of Directors is doing a good job handling their investment (Kaplan 1995). As such, the existing shareholders of the company need financial reporting to assess whether their investments are worthwhile. Prospective investors can utilize them to judge whether the company presents a better investment option compared to others in the industry and in general. The all important tax collections that government authorities perform are b ased on the financial statements of the companies which make them important for the Government (Watts 2003). Even the employees of the company, who are organized in the form of labor unions in many countries, use the financial statements to assess the company's performance and negotiate for compensation and promotion with the management. Financial analysts and those on the
HRM Innovation and Change Essay Example | Topics and Well Written Essays - 500 words - 2
HRM Innovation and Change - Essay Example The chapter elaborates that the traditional role of managers were confined to the well defined parameters of organizationââ¬â¢s goals and management guidelines. Leadership, on the other hand, basically refers to people who have the capacity to bring about changes in other people. Indeed, leaders create visions and goals whereas the managers and administrators work towards achieving them. Hence, in the contemporary environment competitive business, managerial leadership has become the need of the hour. The examples of the dynamic leadership of Leahy of Tesco and Oââ¬â¢Leary of Ryanair illustrates that to develop effectiveness in strategic change, flexible approach to managerial leadership that is more labor friendly needs to be adopted. It should also believe in developing joint goals and objectives that are mutually beneficial, thus fostering mutual beliefs and better understanding of each others value system. Project can broadly be defined as a specific time bound work with specific objectives and goals; budget; and resources. I believe that the successful completion of project therefore, requires teamwork that is defined by shared leadership. Leadership helps to promote smooth functioning of the various processes within the parameters of project goals. The cut throat business environment demands dynamic leadership who strives to create value based mission and inculcates confidence amongst the various stakeholders. Indeed, the project management helps provide the tools to achieve project goals through well planned strategy. At the same time, the managerial leadership would not only facilitate an intangible stability among the team members but also provide impetus for improved performance that result in efficient and time bound completion of the

What Happened to Coca Cola Companys challenges of Coca Cola Case Study
What Happened to Coca Cola Companys challenges of Coca Cola - Case Study Example Many challenges and companyââ¬â¢s fiasco are caused by intolerant policy of the company directed on racial, gender or religious discrimination against its employees. On the example of Coca Cola failures on the basis of racial discrimination issues, it is clearly seen that careful and equitable attitude to all employees is a guarantee of the companyââ¬â¢s success and a protection against companyââ¬â¢s failures. What about diversity, Coke? A famous lawsuit in 1999, which accused the company of racial discrimination against black employees, even after a challenging resolution, resulted in further racial persecutions in the company (What Happened to Coca Cola? p. 264). It would be better for Coca Cola to prevent incidents of racial discrimination at work, because the major part of potential clients is ethnic minorities. Accoring to Joe Solmonese, President, Human Rights Campaign, ââ¬Å"The Coca-Cola Company is a model employer for diversity and inclusion within its own work for ce and as a member of the larger business community. Its leadership on lesbian, gay, bisexual and transgender equality in the workplace is not only reflected in its long-standing achievement of 100 percent on the Corporate Equality Index, but in its principled support of anti-discrimination legislation that would protect every worker in the United States from being judged on the basis of their sexual orientation or gender identityâ⬠(Creating an inclusive workplace). ... In reality, it was evident that Coca Cola appreciated ethnic minorities as their customers and not employees. The Task Force underlined that it was relevant to evaluate career opportunities for white employees with career opportunities for black employees. In spite of the fact that the company hired a third of employees from ethnic minorities, top positions of the company were taken by white employees. It would be relevant to promote to the higher rank positions black employees and in such a way, other employees would realize that they have a real chance to occupy a better position in the company. That is why the majority of plaintiffs did not miss their chance and joined other plaintiffs in the famous lawsuit of 1999. People felt like having a real opportunity to renovate just and tolerant policy at workplace. Unfortunately, their hard struggle did not lead to a complete success. The issues of diversity are still believed to be invented by managers in the company. There is no proof or evidence that there are many examples of career promotion among black employees in the Coca Cola Company. Consequently, the fact that black employees felt indignant and cooperated in the name of equitable attitude at work may be justified. In accordance with Parker, steps made by black employees (plaintiffs) could be explained with regards to Parkerââ¬â¢s triangle ââ¬Å"The Emotional Connection of Distinguishing Differences and conflictâ⬠. He explains that emotions of black employees were hurt and they had no other way out, but to join to other claimants and to fight against racial discrimination in the company. Conclusion Thus, we can claim that Coca Cola made fake attempts to reach diversity in the company. In the majority of cases managers were just saying some words describing
Motivation Speech or Presentation Example | Topics and Well Written Essays - 500 words
Motivation - Speech or Presentation Example This is useful to the organization because it will manage to achieve its own objectives, satisfying its customers and the various stakeholders of an organization. Take for example a cashier serving customers in a retailing organization; a cashier who is well motivated will be (Higgins, 2012); On this basis, the advantages of motivating the employees of an organization will result to the production of high quality work (Karabenick and Urdan, 2010). It is always the role of a manager to motivate his own work force. There are a number of ways and methods of motivating the workforce of an organization. These methods include, It is important to denote that these activities fall under a motivational theory. There are a number of motivational theories developed by scholars of management and psychology. One such theory is the expectancy theory. This is a theory developed by Victor Vroom, and it gives a proposal that people will behave in a certain manner, because of a reward that is attached to the action under consideration (Higgins, 2012). For example, an employee in a manufacturing organization will decide work double shifts in case of shortages of work force, and in return, the employee will expect to get some compensation and praise from the management. Another theory is the equity theory developed by John Adams in 1963. This theory denotes that employees of an organization will be motivated if they are treated equally. For example, if employees of an organization perform the same job, i.e. they are both accountant, then the management should pay them an equal salary (Karabenick and Urdan, 2010). Failure for an organization to treat its employees equally could result to a de-motivated work force. Another theory is the hierarchy of needs theory by Abraham Maslow (Higgins, 2012). This theory denotes that the employees of an organization have several needs, and they are hierarchical in

Ethics The Element of Moral Philosophy by Rachels, Meditations ( Essay
Ethics The Element of Moral Philosophy by Rachels, Meditations ( Marcus Aurellius), A man For All Seasons (Bolt) - Essay Example Additionally, the origin of morals and moral behavior is relatively unknown; as is what components a person must consider when deciding whether his or her actions would be considered moral. Unlike many consequentialists, Kant asserts deontological, or "Duty Based" morals. Essentially, morals come directly from the will of the person taking action; that person will do the right thing simply because it is the right thing to do. This approach to ethics is the easiest to teach, the first people learn, and the most cut-and-dry approach to ethics and moral influence available. The Kantian approach to morality relies heavily on universal acceptance and implementation of "laws" such as whether or not a person should lie, steal, or murder. Clearly, to lie, steal, or murder is wrong; therefore a moral person will never lie, will never steal, and will never murder another person. The idea of "Universal Acceptance and Application of Laws" is known as the Categorical Imperative. Kant describes this Categorical Imperative as a personal choice: act in a manner that you would like to see become a universal law. This is somewhat akin to the "Golden Rule" - in a sense. In essence, this ideal asserts that while a person is deciding whether or not to do something (such as lie) to first consider whether or not that action should be done to him. To work with the example of lying: if a person does not believe that lying should be a universally accepted practice, then that person - through logic and reasoning - should not lie under any circumstances. Deontological ethics are rarely concerned with the outcome of an action - only the action itself is measured in terms of moral evaluation. Therefore, the Kantian approach to ethics is largely impartial and more objective than other views of moral behavior. As stated by Kant, there are no exceptions within this approach to ethics and morals. If it is wrong to lie, then at no time should a person lie. No matter the outcome of a situation, deontological ethics define a person as morally right if that person did not lie. For example, people seeking employment often have to write up resumes and/or fill out job applications. Some jobs require a certain amount of experience or training within the profession - or possible a particular personality - to consider an interviewee for employment. While filling out the application, duty-based ethics would require that a person be forthright with his or her information and personality traits - even if doing so may cost him or her employment. If the result of being honest results in the loss or foreclosure of the home, the act of being honest about his or her experiences on the job application is still measured as morally correct. The Kantian approach to ethics and morals is not without its flaws; some concepts simply cannot be categorized as "universal" and other should not. For example, if one persons morals infringes upon the rights or morals of another person. The use of contraceptives can be used as an example of this. If people were to universally stop the use of contraceptives, the world would become much more populated than it already is. Teen pregnancy would being to increase, and subsequently the number of abortions and adoptions would increase proportionally. However, if everyone universally began using

Motivation - Speech or Presentation Example This is useful to the organization because it will manage to achieve its own objectives, satisfying its customers and the various stakeholders of an organization. Take for example a cashier serving customers in a retailing organization; a cashier who is well motivated will be (Higgins, 2012); On this basis, the advantages of motivating the employees of an organization will result to the production of high quality work (Karabenick and Urdan, 2010). It is always the role of a manager to motivate his own work force. There are a number of ways and methods of motivating the workforce of an organization. These methods include, It is important to denote that these activities fall under a motivational theory. There are a number of motivational theories developed by scholars of management and psychology. One such theory is the expectancy theory. This is a theory developed by Victor Vroom, and it gives a proposal that people will behave in a certain manner, because of a reward that is attached to the action under consideration (Higgins, 2012). For example, an employee in a manufacturing organization will decide work double shifts in case of shortages of work force, and in return, the employee will expect to get some compensation and praise from the management. Another theory is the equity theory developed by John Adams in 1963. This theory denotes that employees of an organization will be motivated if they are treated equally. For example, if employees of an organization perform the same job, i.e. they are both accountant, then the management should pay them an equal salary (Karabenick and Urdan, 2010). Failure for an organization to treat its employees equally could result to a de-motivated work force. Another theory is the hierarchy of needs theory by Abraham Maslow (Higgins, 2012). This theory denotes that the employees of an organization have several needs, and they are hierarchical in

Social Class Differences in Education Essay Example for Free
Social Class Differences in Education Essay The claim that social class differences in education through school factors is supported by the interactionists such as George H. Mead. They believe that labelling theory encourages the educational achievement in different social classes. The labelling theory is when the teacher identifies major characteristics of a student. Research shows that teachers are more likely to label middle class children as bright and well behaved but working class children as naughty and disruptive. Following the label being attached on the child is self fulfilling prophecy, this is when the child will respond and act according to the label being placed on them, so a middle class student will act well behaved and complete the work that is set whereas the working class student will disrupt and not complete the work set and therefore not do well in exams. This shows that labelling working and middle class students affects the educational achievements because of their social class. However George H.Ã Mead can be criticised by material/cultural deprivation. Material deprivation is when the child doesnt have the right equipment for school e. g. books, and cultural deprivation is when the children havent been given the correct norms and values for attitudes to education. This shows that it is not only school factors that affect the differences in education achievement but it is also home factors. Marxists such as Willis would argue that counter school subcultures are the reason why different social class are achieving and underachieving. He claims that working class boys reject the whole idea of school and see school as a place of laughs and a matter of amusement because they do not have the correct norms and values, the see schools as boring so the disrupt lessons and breaking school rules. This behaviour will lead to low grades and therefore low pay jobs in the future. This shows that difference in social class results to different educational achievement. It can be argued that the working class children do not think about the uture also known as cultural capital, working class children only see how they should enjoy themselves in the present time and not what the rewards of education will be later on in life, this could be due to the rise in lone parent mothers and boys do not see a role model father and therefore do not value education, this shows that it is not only school factors that affect the educational achievement but it is home factors as well. Gillborn and Youdell argued that examination sets are split into two tiers, foundation and higher. Pupils that are entered for the foundation paper can not achieve higher than a C, pupils who are entered in for the higher paper are able to achieve A*. middle class students are more likely to be entered in the higher paper and working class are placed in the foundation. This shows that educational achievement is because of school factors and that working class pupils are not given a fair opportunity to education. However Sugarman would argue that educational achievement is not only because of school factors it is also home factors this could be due to class subcultures. He describes working class pupils as fatalistic and that they accept their position rather than trying to improve this. Pupils are not given the motivation for parents to try and improve. Evidence shows that there are may reasons why difference in social class leads to different educational achievements so therefore evidence remains inconclusive.

Extraction of Essential Oils Using Steam Distillation
Extraction of Essential Oils Using Steam Distillation Acknowledging about the importance of plants and its medicinal value research work is being done on the plant material. There are also over 200 references to aromatics, incense and ointments in the Old and New Testaments; Frankincense, Myrrh, Galbanum, Cinnamon, Cassia, Rosemary, Hyssop and Spikenard are noted for being used for anointing rituals and healing of the sick. Research has confirmed centuries of practical use of essential oils, and we now know that the fragrant pharmacy contains compounds with an extremely broad range of biochemical effects. The oils normally bear the name of the plant species from which they are derived. Essential oils are so termed as they are believed to represent the very essence of odor and flavor. The recovery of essential oil (the value added product) from the raw botanical starting material is very important since the quality of the oil is greatly influenced during this step. There are a variety of methods for obtaining volatile oils from plants. S team distillation method is found to be one of the promising techniques for the extraction of essential oil from plants as reputable distiller will preserve the original qualities of the plant and is being done in Clevenger apparatus. Analysis of Essential oil is done Gas Chromatography which gives us some indications of the quality and authenticity of the oil. CHAPTER 1: INTRODUCTION Essential oils contain highly volatile substances that are isolated by a physical method or process from plants of a single botanical species. The oils normally bear the name of the plant species from which they are derived. Essential oils are so termed as they are believed to represent the very essence of odor and flavor. Essential oil plants and culinary herbs include a broad range of plant species that are used for their aromatic value as flavorings in foods and beverages and as fragrances in pharmaceutical and industrial products. Essential oils derive from aromatic plants of many genera distributed worldwide. Oils are used in the embalming process, in medicine and in purification rituals. There are also over 200 references to aromatics, incense and ointments in the Old and New Testaments. Research has confirmed centuries of practical use of Essential Oils, and we now know that the fragrant pharmacy contains compounds with an extremely broad range of biochemical effects. There are about three hundred essential oils in general use today by professional practitioners. Continual bombardment of viral, bacterial, parasitic and fungal contamination occurs in our body. Essential oils are a great benefit to help protect our bodies and homes from this onslaught of pathogens. Immune system needs support and these essential oils can give the required endorsement. [1] Steam distillation is used in the extraction of Essential Oil from the plant material. It is a special type of distillation or a separation process for temperature sensitive materials like oils, resins, hydrocarbons, etc. which are insoluble in water and may decompose at their boiling point. The fundamental nature of steam distillation is that it enables a compound or mixture of compounds to be distilled at a temperature substantially below that of the boiling point(s) of the individual constituent(s). Essential Oil contains components with boiling points up to 200à °C or higher temperatures. In the presence of steam or boiling water, however, these substances are volatilized at a temperature close to 100à °C, at atmospheric pressure. [2] Analysis of Essential Oil is done by using Gas Chromatography with Mass Spectrometer. The qualitative and quantitative analysis is done to know the constituents in the oil and the percentage of components present in the oil respectively, by doing so we can know the purity of that particular oil. [3] CHAPTER 2:à LITERATURE REVIEW It is estimated that there are 250,000 to 500,000 species of plants on Earth. A relatively small percentage (1 to 10%) of these is used as foods by both humans and other animal species. It is possible that even more are used for medicinal purposes (Moerman, D. E. 1996). Moerman (1996) reported that while 625 species of plants have been used by various Native American groups as food, 2,564 have found use as drugs. According to his calculations, this leaves approximately 18,000 species of plants which were used for neither food nor drugs. [4] Plant oils and extracts have been used for a wide variety of purposes for many thousands of years (Jones 1996). These purposes vary from the use of rosewood and cedar wood in perfumery, to flavoring drinks with lime, fennel or juniper berry oil, and the application of lemongrass oil for the preservation of stored food crops. In particular, the antimicrobial activity of plant oils and extracts has formed the basis of many applications, including raw and processed food preservation, pharmaceuticals, alternative medicine and natural therapies. Since ancient times, herbs and their essential oils have been known for their varying degrees of antimicrobial activity. More recently, medicinal plant extracts were developed and proposed for use in food as natural antimicrobials. 2.1 DEFINITION: An essential oil is a concentrated, hydrophobic liquid containing volatile aroma compounds from plants. Essential oils are also known as volatile, ethereal oils or aetherolea, or simply as the oil of the plant from which they were extracted, such as oil of clove. Oil is essential in the sense that it carries a distinctive scent, or essence, of the plant. [5] Essential oils are frequently referred to as the life force of plants. These essential oils are extracted from flowers, leaves, stems, roots, seeds, bark, and fruit rinds. The amount of essential oils found in these plants can be anywhere from 0.01 percent to 10 percent of the total. These oils have potent antimicrobial factors, having wide range of therapeutic constituents. These oils are often used for their flavor and their therapeutic or odoriferous properties, in a wide selection of products such as foods, medicine, and cosmetics. Only pure oils contain a full spectrum of compounds that cheap imitations simply cannot duplicate. [5] 2.2 CHEMICAL CONSTITUENTS OF ESSENTIAL OILS: An Essential Oil contains more than 200 chemical components, but some are many times more complex. Essential oils consist of chemical compounds which have hydrogen, carbon and oxygen as their building blocks. They can be essentially classified into two groups: Volatile fraction: Essential oil constituting of 90-95% of the oil in weight, containing the monoterpene and sesquiterpene hydrocarbons, as well as their oxygenated derivatives along with aliphatic aldehydes, alcohols, and esters. Nonvolatile residue: This comprises 1-10% of the oil, containing hydrocarbons, fatty acids, sterols, carotenoids, waxes, and flavonoids. However the properties of these components can change. For example, the components from the oils extracted from plants can change according to how, when and where these plants are grown and harvested. [6] The constituents can be again subdivided into 2 groups, such as the hydrocarbons which are made up of mostly terpenes and the oxygenated compounds which are mainly alcohols, aldehydes, esters, ketones, phenols and oxides. Some of the common components are listed below along with their properties. Alcohols: Alcohols are generally considered safe and have a very low or totally absent toxic reaction in the body or on the skin and so can be used on children. They are extremely useful due to their antiviral, antibacterial and antiseptic properties. Alcohols are present either as a free compound or combined with a terpene or ester and are found in ylang -ylang and lavender as linalool, geraniol in geranium and palmarosa and citronellol found in rose, lemon and eucalyptus. Other alcohols include menthol, nerol and benzyl alcohol. Alderhydes: Alderhydes are found in lemon-scented oils such as Melissa, lemon verbena, citronella etc. and include citral, citronellal and neral. They generally have sedative qualities with specific antiseptic properties. Other known alderhydes include benzaldehyde, cinnamic alderhyde and perillaldehyde. Essential oils containing alderhydes are helpful in treating inflammation, Candida and viral infections. [6] Hydrocarbon: Building blocks of Essential Oil are hydrogen and carbon. Basic Hydrocarbon found in plants is isoprene having the following structure. (Isoprene) Terpenes: These components generally have names ending with ene. Some of them are limonene, pinene, piperene, camphene etc. These components act as an antibacterial, antiviral, anti-inflammatory, antiseptic, antiviral and bactericidal. These are further categorized into monoterpene, sesquiterpene and diterpenes. When two of the isoprene units are joined head to tail, the result is a monoterpene, when three are joined, its a sesquiterpene and similarly four linked isoprene units are diterpenes. Monoterpene [C10H16]: Monoterpene are naturally occurring compounds, the majority being unsaturated hydrocarbons (C10).But some of their oxygenated derivatives such as alcohols, Ketones, and carboxylic acids known as monoterpenoids. (Limonene) (Menthol) Two isoprene units are present in these branched-chain C10 hydrocarbons and are widely distributed in nature with more than 400 naturally occurring monoterpenes. Moreover, besides being linear derivatives (Geraniol, Citronellol), the monoterpenes can be cyclic molecules (Menthol Monocyclic; Camphor bicyclic; Pinenes (ÃŽà ± and ÃŽà ²) Pine genera as well. Thujone (a monoterpene) is the toxic agent found in Artemisia absinthium (wormwood) from which the liqueur absinthe, is made. Borneol and camphor are two common monoterpenes. Borneol, derived from pine oil is used as a disinfectant and deodorant. Camphor is used as a counterirritant, anesthetic, expectorant, and antipruritic, among many other uses. Sesquiterpene: Sesquiterpenes are biogenetically derived from farensyl pyrophosphate and in structure may be linear, monocyclic or bicyclic. They constitute a very large group of secondary metabolites, some having been shown to be stress compounds formed as a result of disease or injury. These are having properties like anti-inflammatory, anti-septic, analgesic and anti-allergic. Sesquiterpene Lactones: These are available as farnesene in chamomile and lavender. They not only have proved to be of interest from chemical and chemotaxonomic point of view, but also possess many antitumor, anti-leukemia, cytotoxic and antimicrobial activities. Chemically the compounds can be classified according to their carboxylic skeletons; thus, guaianolides, pseudoguaianolides, eudesmanolides, eremophilanolides, xanthanolides, etc. can be derived from the germacranolides. Structural features of all these compounds are associated with much of the biological activity. For example beta-caryophyllene in basil and black pepper Diterpenes: Isoprene has been an integral part in most of the components as there are four isoprene units in Diterpenes. By Stem Distillation method we cannot detect Diterpenes as this molecule is too heavy to allow for evaporation, so it is rarely found in distilled Essential Oils. Diterpenes occur in all plant families and consist of compounds having a C20 skeleton. There are about 2500 known Diterpenes that belong to 20 major structural types. Derivatives of Diterpenes are plant hormones Gibberellins and phytol occurring as a side chain on chlorophyll. The biosynthesis occurs in plastids and interestingly mixtures of monoterpenes and diterpenes are the major constituents of plant resins. In a similar manner to monoterpenes, Diterpenes arise from metabolism of geranyl geranyl pyrophosphate (GGPP). Therapeutically Diterpenes have limited importance and are used in certain sedatives (coughs) as well as in antispasmodics and anxiolytics. Alcohols: Naturally Alcohols exist either as a free compound or combined with a terpenes or ester. When terpenes are attached to an oxygen atom, and hydrogen atom, the result is an alcohol. When the terpene is monoterpene, the resulting alcohol is called a monoterpenol. Alcohols are not and are suitable to body or skin. Therefore, they are considered safe to use. Some of these properties are anti-septic, anti-viral, bactericidal and germicidal. Some of the examples are linalool found in ylang-ylang and lavender, geraniol in geranium and rose and nerol in neroli. Aldehydes: Aldehyde containing Essential Oils are effective in treating candida and other fungal infections. Some of these properties are anti-fungal, anti-inflammatory, anti-septic, anti-viral, bactericidal, disinfectant, and sedative. Aldehydes are present as citral in lemon, Citronellal in lemongrass, lemon balm and citrus eucalyptus. Acids: Generally Organic acids are found in very small quantities in their free state within Essential Oils. Plant acids act as components or buffer systems to control acidity. These also act anti-inflammatory. Examples are cinnamic and benzoic acid in benzoin, Citric and lactic. Esters: Esters are formed through the reaction of alcohols with acids. Essential oils containing esters are used for their soothing, balancing effects. Because of the presence of alcohol, they are effective antimicrobial agents. Medicinally, esters are characterized as antifungal and sedative, with a balancing action on the nervous system. They generally are free from precautions with the exception of methyl salicylate found in birch and wintergreen which is toxic within the system. Examples are linlyl acetate in bergamot and lavender and Geranyl formate in geranium. Ketones: Ketones found in plants are used for upper respiratory complaints. They assist the flow of mucus and ease congestion. Essential oils containing ketones are beneficial for promoting wound healing and encouraging the formation of scar tissue. Ketones are (not always) very toxic. The most toxic ketone is Thujone found in mugwort, sage, tansy, thuja and wormwood oils. Other toxic ketones found in essential oils are pulegone in pennyroyal, and pinocamphone in hyssops. Some non-toxic ketones are jasmone in jasmine oil, fenchone in fennel oil, carvone in spearmint and dill oil and menthone in peppermint oil. Lactones: Lactones are known to be particularly effective for their anti-inflammatory action, possibly by their role in the reduction of prostaglandin synthesis and expectorant actions. Lactones have an even stronger expectorant action than ketones. [Previous thesis] 2.3 ADVANTAGES OF ESSENTIAL OIL: AROMATHERAPHY: Aromatherapy is a form of alternative medicine that uses volatile plant materials, known as essential oils, and other aromatic compounds for the purpose of altering a persons mood, cognitive function or health. Science has discovered that our sense of smell plays a significant role in our overall health. Since ancient times Essential Oils have been used in medicine because of their medicinal properties, for example some oils have antiseptic properties. In addition, many have an uplifting effect on the mind, though different essential oils have different properties. Working of Essential Oil in Aromatherapy: when Essential Oil is inhaled it goes directly from olfactory system to limbic system of the brain. Brain responds to the particular scent affecting our emotions and chemical balance. Essential Oils also absorbed by the skin and carried throughout the body via the circulatory system to reach all internal organs. We can be benefited by choosing carefully the desired and suitable oils which can promote overall health. Benefits depend upon the unique nature of each persons response to an aromatic stimulus. [1] Importance of Essential Oil in pharmaceutics: Essential Oils have versatile applications in pharmaceutics. Some of the applications are listed below. Antiseptics: The antiseptic properties of Essential Oil make them active against wide range of bacteria as on antibiotic resistant strains. In addition to this they are also against fungi and yeasts. The most common sources of essential oils used as antiseptics are: Cinnamon, Thyme, Clover, Eucalyptus, Culin savory, Lavender. Citral, geraniol, linalool and thymol are much more potent than phenol. [1] Expectorants and diuretics: When used externally, essential oils like (Lessence de terebenthine) increase microcirculation and provide a slight local anesthetic action. Till now, essential oils are used in a number of ointments, cream and gels, whereby they are known to be very effective in relieving sprains and other articular pains. Oral administration of essential oils like eucalyptus or pin oils, stimulate ciliated epithelial cells to secrete mucus. On the renal system, these are known to increase vasodilation and in consequence bring about a diuretic effect. Spasmolytic and sedative: Essential oils from the Umbellifereae family, Mentha species and verbena are reputed to decrease or eliminate gastrointestinal spasms. These essential oils increase secretion of gastric juices. In other cases, they are known to be effective against insomnia. METHODS OF EXTRACTION: The following are the methods of extraction of Essential Oil and their drawbacks. 2.4.1 Solvent-Extraction: In the Solvent-Extraction method of Essential Oils recovery, an extracting unit is loaded with perforated trays of essential oil plant material and repeatedly washed with the solvent. A hydrocarbon solvent is used for extraction. All the extractable material from the plant is dissolved in the solvent. This includes highly volatile aroma molecules as well as non-aroma waxes and pigments. The extract is distilled to recover the solvent for future use. The waxy mass that remains is known as the concrete. The concentrated concretes are further processed to remove the waxy materials which dilute the pure essential oil. To prepare the absolute from the concrete, the waxy concrete is warmed and stirred with alcohol (ethanol). During the heating and stirring process the concrete breaks up into minute globules. Since the aroma molecules are more soluble in alcohol than the waxes, an efficient separation of the two results. This is not considered the best method for extraction as the solvents can leave a small amount of residue behind which could cause allergies and effect the immune system. 2.4.2 Maceration: Maceration actually creates more of infused oil rather than an Essential Oil. Plant matter is soaked in vegetable oil, heated and strained at which point it can be used for massage. This method is not desirable because it changes the composition of oil. 2.4.2 Cold Pressing: This method is used to extract the Essential Oils from citrus rinds such as orange, lemon, grapefruit and bergamot. This method involves the simple pressing of the rind at about 120 degrees F to extract the oil. The rinds are separated from the fruit, are ground or chopped and are then pressed. The result is a watery mixture of essential oil and liquid which will separate given time. Little alteration from the oils original state occurs these citrus oils retain their bright, fresh, uplifting aromas like that of smelling a wonderfully ripe fruit. The drawback of this method is, oils extracted using this method have a relatively short shelf life. 2.4.3 Effleurage: This is one of the traditional ways of extracting oil from flowers. The process involves layering fat over the flower petals. After the fat has absorbed the essential oils, alcohol is used to separate and extract the oils from the fat. The alcohol is then evaporated and the Essential Oil is collected. 2.4.4 Super Critical CO2 Extraction: Supercritical CO2 extraction (SCO2) involves carbon dioxide heated to 87 degrees F and pumped through the plant material at around 8,000 psi, under these conditions; the carbon dioxide is likened to a dense fog or vapor. With release of the pressure in either process, the carbon dioxide escapes in its gaseous form, leaving the Essential Oil behind. The usual method of extraction is through steam distillation. After extraction, the properties of a good quality essential oil should be as close as possible to the essence of the original plant. The key to a good essential oil is through low pressure and low temperature processing. High temperatures, rapid processing and the use of solvents alter the molecular structure, will destroy the therapeutic value and alter the fragrance. 2.4.5 Turbo Distillation Extraction: Turbo distillation is suitable for hard-to-extract or coarse plant material, such as bark, roots, and seeds. In this process, the plants soak in water and steam is circulated through this plant and water mixture. Throughout the entire process, the same water is continually recycled through the plant material. This method allows faster extraction of essential oils from hard-to-extract plant materials. Dr.A.Sahoo et al have studied that Steam Distillation is a special type of distillation or a separation process for temperature sensitive materials like oils, resins, hydrocarbons, etc. which are insoluble in water and may decompose at their boiling point. The temperature of the steam must be high enough to vaporize the oil present, yet not so high that it destroys the plants or burns the essential oils. The experiment has been carried out for the extraction of oil from Eucalyptus which has high essential oil content. Such Eucalyptus essential oil, which have been used as perfume and chemical raw materials for a long time, are now been studied as renewable sources of energy. G. Anitescu et al have studied that ripe fruits of Coriander sativum L. were extracted by steam distillation and by supercritical fluid extraction (SFE), using CO2 in a two-stage separation system. An inexpensive thermal expansion procedure for supercritical fluid delivery has been developed. The identification of components was performed by gas chromatography and mass spectrometry (GCà ±MS). The percentage composition of the 40 identified compounds was compared with the composition of commercial coriander oil extracted by hydro distillation. Roy Teranishi et al have studied that system combines steam distillation and liquid-liquid extraction to recover volatiles from fats and oils. Oil is pumped in at the top of a spinning-band distillation column, in which the oil is heated to100 C and spread to a thin film. As the oil film drops down to the pot, steam, which is introduced at the bottom, travels upward to strip the volatiles from the oil. The steam distillate is extracted in a liquid-liquid extractor incorporated in the system, and the extracted water is recycled as steam. Stripped oil in the pot serves as a liquid seal to force steam up the column. The level of the oil in the pot is maintained automatically by an overflow system. Many liters of oil can be pumped through this system to be stripped of volatiles by steam. The volatiles can be isolated easily from the small amount of solvent recycled in the liquid-liquid extractor. Referring to the above literature review, it was found that Steam Distillation method is an appropriate and economical method for extraction of Essential Oil. 2.4.6 Extraction of Essential Oils Using Steam distillation Method: Steam distillation is a special type of distillation or a separation process for temperature sensitive materials like oils, resins, hydrocarbons, etc. which are insoluble in water and may decompose at their boiling point. The fundamental nature of steam distillation is that it enables a compound or mixture of compounds to be distilled at a temperature substantially below that of the boiling point(s) of the individual constituent(s). Essential oils contain substances with boiling points up to 200à °C or higher temperatures. In the presence of steam or boiling water, however, these substances are volatilized at a temperature close to 100à °C, at atmospheric pressure. Fresh, or sometimes dried, botanical material is placed in the plant chamber of the still and the steam is allows to pass through the herb material under pressure which softens the cells and allows the Essential Oil to escape in vapor form. The temperature of the steam must be high enough to vaporize the oil present, yet not so high that it destroys the plants or burns the Essential Oils.à Besides the steam tiny droplets of Essential Oil evaporates and travel through a tube into the stills condensation chamber. Here Essential Oil vapors condense with the steam.à The essential oil forms a film on the surface of the water.à To separate the Essential Oil from the water, the film is then decanted or skimmed off the top.à The remaining water, a byproduct of distillation, is called floral water, distillate, or hydrosol. It retains many of the therapeutic properties of the plant, making it valuable in skin care for facial mists and toners (A solution containing chemicals that can c hange the color of a photographicà print).à In certain situations, floral water may be preferable to be pure essential oil, such as when treating a sensitive individual or a child, or when a more diluted treatment is required. Rose hydrosol, for example, is commonly used for its mild antiseptic and soothing properties, as well as its pleasing floral aroma. A number of factors determine the final quality of a steam distilled essential oil. Apart from the plant material, most important are time, temperature and pressure, and the quality of the distillation equipment. Essential oils are very complex products. Each is made up of many, sometimes hundreds, of distinct molecules which come together to form the oils aroma and therapeutic properties. Some of these molecules are fairly delicate structures which can be altered or destroyed by adverse environmental conditions. So, much like a fine meal is more flavorful when made with patience, most oils benefit from a long, slow cooking process. It is possible that longer distillation times may give more complete oil. It is also possible however, that longer distillation time may lead to the accumulation of more artifacts than normal. This may have a curious effect of appearing to improving the odor, as sometimes when materials that have a larger number of components are sniffed, the perception i s often of slightly increased sophistication, added fullness and character, and possibly, and extra pleasantness. Advantages of using Steam Distillation: The advantage of Steam Distillation is that it is a relatively cheap process to operate at a basic level, and the properties of oils produced by this method are not altered. As steam reduces the boiling point of a particular component of the oil, it never decomposes in this method. This method apart from being economical, it is also relatively faster than other methods. CHAPTER 3:à EXPERIMENTAL WORK 3.1 Experimental Setup: The schematic diagram of experimental setup is shown below. The experiment was conducted in a Clevengers Apparatus. Apparatus consist of one round bottom flask of 1000ml which is connected with another two way round flask which holds raw material. The top flask is connected with condenser through the connecter. The separating funnel is used for the separation of essential oil and water. 3.2 Experimental Procedure: Fresh leaves (rosemary) or bark (cinnamon) are cut into pieces less than 2 X 2 cm within half a day after collection and 150-200 g boiled with 500 ml of distilled water in a Clevenger apparatus until oil distillation ceased after 5-6 h. The volume of essential oils was determined from a calibrated trap. The essential oils in the distillate were dried over anhydrous Na2SO4 and kept in the freezer. 3.3 Analysis of Essential Oils: Analysis of Essential Oil was done using Gas Chromatography with Mass spectrometer to know the composition of oil and to the quantity of each composition. 3.3.1 Gas Chromatography-Mass Spectrometer: Gas Chromatography-Mass Spectrometry (GC-MS) is a method that combines the features of gas-liquid chromatography and mass spectrometry to identify different substances within a test sample. Applications of GC-MS include drug detection, fire investigation, environmental analysis, explosives investigation, and identification of unknown samples. Additionally, it can identify trace elements in materials that were previously thought to have disintegrated beyond identification. [7] Instrumentation: The GC-MS is composed of two major building blocks: the gas chromatograph and the mass spectrometer. The gas chromatograph utilizes a capillary column which depends on the columns dimensions (length, diameter, film thickness) as well as the phase properties (e.g. 5% phenyl polysiloxane). The difference in the chemical properties between different molecules in a mixture will separate the molecules as the sample travels the length of the column. The molecules take different amounts of time (called the retention time) to come out of (elute from) the gas chromatograph, and this allows the mass spectrometer downstream to capture, ionize, accelerate, deflect, and detect the ionized molecules separately. The mass spectrometer does this by breaking each molecule into ionized fragments and detecting these fragments using their mass to charge ratio. These two components, used together, allow a much finer degree of substance identification than either unit used separately. It is not possible to make an accurate identification of a particular molecule by gas chromatography or mass spectrometry alone. The mass spectrometry process normally requires a very pure sample while gas chromatography using a traditional detector (e.g. Flame Ionization Detector) detects multiple molecules that happen to take the same amount of time to travel through the column (i.e. have the same retention time) which results in two or more molecules to co-elute. Sometimes two different molecules can also have a similar pattern of ionized fragments in a mass spectrometer (mass spectrum). Combining the two processes makes it extremely unlikely that two different molecules will behave in the same way in both a gas chromatograph and a mass spectrometer. Therefore when an identifying mass spectrum appears at a characteristic retention time in a GC-MS analysis, it typically lends to increased certainty that the analyte of interest is in the sample. [7] 3.4 Experimental Observation: Experiment had been conducted using different plant materials at different temperatures and time of heating, keeping pressure constant (atmospheric pressure). CHAPTER 4:à RESULTS AND DISCUSSION 4.1 Inferences: Volume of Essential Oil obtained from a particular plant material was different for different temperatures and at a particular temperature for different time of heating. Volume of Essential Oil obtained is less in comparison to hydrosol of the same plant material. Its variation along with temperature and time of heating is shown in graphs drawn below. 4.1.1 Graph showing variation of Volume of Essential Oil against Temperature, obtained from Orange peels. From the graph we can observe that volume of Essential Oil obtained from orange peels is almost increasing linearly with Temperature, if we ignore the slight decline in volume at 900C. The decline may be due to leakage of vapor during Steam Distillation or because of improper decantation. 4.1.2 Graph showing variation of Volume of Essential Oil against Temperature, obtained from Eucalyptus leaves. From the above graph we can observe that volume of Essential Oil obtained is negligible before the components of the oil reach to their boiling
